no sorry, that didnt work. i tried chmodding and chowning what you told me to do, and yeh looks like php still isnt supported for the domain without the www.
but i think if i can get wot you told me to do before working, by adding mydomain.com as a co-domain, i think that would work.
But even in co-domain, it still asks for a hostname, what am i suppose to put in there? I cant put www again, or else it would be like www.www.mydomain.com
